Conversation
This additionally applies to `TypesRef` and this PR applies a few changes: * Going from a `TypeId` to a `Type` is now done with `&types[id]` or `types.get(id)` instead of `type_from_id(id).unwrap()`. * All index-based accessors return a `T` instead of `Option<T>`. Fallibility is possible through the `*_count()` methods for embedders to test if necessary, but otherwise almost all accesses were followed by `.unwrap()` anyway. * Conversions from `Type` to a sub-component which were previously `as_foo_type(&self) -> Option<&Foo>` are now expressed as `unwrap_foo(&self) -> &Foo`. This renames `as` to `unwrap` to highlight the panicking behavior and additionally drops the `_type` suffix since that's implied on everything anyway. * The `type_at` function and its `core: bool` argument are removed in favor of `core_type_at` and `component_type_at` functions. * The `func_type_at` function was removed as it can be achieved through combining other functions. * Some methods which returned `&T` changed to return a `TypeId` which represents `T` for consistency. This is inspired by comments on bytecodealliance#1094 and is something I've wanted to address for awhile and will ideally make the `Types` API a bit more ergonomic to use with fewer conversions and less `.unwrap()` boilerplate without any loss of functionality.

How does this code know it has a core type index, rather than a component type index?

That's contextually known since the funcs
map comes from parsing a core wasm module (the input to wasm-tools component new
which is also where the types
type information comes from.
